In blender is was correct but if i change the gray material inside of cockpit i become the same error.

Render with BlenderRender.

I export the model from blender with orge-exporter. I create a new material with jme3-sdk and set baked diffuse, alpha, glow and normal map.

Material My Material : Common/MatDefs/Light/Lighting.j3md {
 MaterialParameters {
    NormalMap : Models/ship/normal.png
    GlowMap : Models/ship/glow.png
    AlphaMap : Models/ship/alpha.png
    DiffuseMap : Models/ship/diffuse.png
    Minnaert : true
 }
AdditionalRenderState {
  Blend Alpha
  FaceCull Off
}

}

I test with and without FaceCull Off and default (i think front).
I add model in queue bucket, Opaque, Transparent and Translucent.

Please help me.

Ok, this question is coming too often now. Usually we have to wait at least three days and now it’s coming almost daily.

Please search the forum for alpha sorting, alpha transparency, alpha depth buffer sorting, etc… you will probably find a bunch of threads on nearly exactly this problem.
